Hi Dave,
Thanks for the response but my research indicated it was a (a10) heating fault and the heating element was indeed open circuit.
This was subsequently replaced and but the same error lights persisted and I couldn’t start a programme.
I have since managed to reset the error by more luck than anything else by switching on/off whilst holding in various buttons.
The appliance is now working perfectly but I would like to know how to do a reset for any future repairs on these appliances.
Cheers.
Noel.
